Consider the design of an optimal linear filter for a zero mean WSS random sequence whereby the sample values during the observation window are given by:
(-1,0,1,2,3,3,2,1,2,3,1,-1,-2,1,0)
1. Obtain the optimal memory M=2 linear predictor coeffecients and the resulting distortion.
2. Show the lattice filter realization of the forward and backward prediction error filters
